Reliable connectivity Data from distant and deep indoor places

CHESTER connects to the internet via LPWAN communication technologies (NB-IoT, LTE-M, and LoRaWAN are supported). Choose the built-in internal antenna or connect an external antenna for any of those options. For diagnostics, parametrization, and device firmware upgrades, CHESTER comes with a Bluetooth Low Energy interface available in modern smart devices and notebooks.

Designed from the ground up as a low‑power device

CHESTER has been designed from the ground up as a low-power device and provides years of operation from the primary lithium cells. Another way to power the device is to use a rechargeable battery backup module with the optional solar photovoltaic panel input. For applications where batteries are not applicable, it is possible to energize the device from a standard 24 V DC line power or 230 V AC line.
